Abstract
Interruptions in three nitrate reductase-related genes, narH, narJ, and moaE, inhibited heterotrophic nitrification in Pseudomonas strain M19. No nitrate was detected in the medium, and nitrification proceeded in the presence of a nitrate reductase inhibitor. Heterotrophic nitrification was greatly stimulated by the addition of nitrate.
摘要
三种与硝酸还原酶相关的基因narH、narJ和moaE的中断，抑制了假单胞菌菌株M19中的异养硝化作用。培养基中未检测到硝酸盐，并且在存在硝酸还原酶抑制剂的情况下硝化作用仍在进行。添加硝酸盐极大地刺激了异养硝化作用。
